What Two Different Types Of Firmware May Be Used On Motherboards?
The BIOS and the UEFI are the two types of firmware that are used on the motherboards. Today, let us discuss each of these types in detail. The term UEFI stands for unified extensible firmware interface. It is called the next-generation interface between the operating system and the platform firmware. The UEFI will replace the antiquated legacy basic input/output system which is shortly called BIOS. The UEFI standard was created by the UEFI consortium. It consists of around 140 technological companies. The main aim to develop the UEFI is to simplify and secure the pre boot environment that preventing the injection of any dangerous code. It is also used to improve interoperability between the systems.
The BIOS has some of the basic limitations that will relate to modern hardware. The BIOS is only limited to the 16-bit processor mode. And it has a memory of one megabyte of the addressable memory. But the UEFI, on the other hand, will supports either the 34 bit or it will support 64-bit processor mode. It can able to access all the system memory.
The BIOS will use the Master Boot Record which is shortly called the MBR. It is used for the disk partitioning scheme and the UEFI uses the newer partitioning scheme called the GPT.
The UEFI is able to support the disk sizes which are greater than the two terabytes with its maximum disk and the partition size, which is 8 to 7 bytes. But by converting the operating system drive partition from MBR to the GPT, is a type of destructive process where the new partitioning scheme that needs to be formatted and the operating system needs to be completely reinstalled.
Without any right process and rules, this process will be an expensive manual effect. We have many security advantages by running the UEFI than the BIOS on the Windows 10 operating system. For example, the secure boot will process against the boot kits, we also have a device guard, credential guard, biometric authentication, and the end-users will also appreciate the startup times that are faster.
And the BIOS is another type of firmware, the term BIOS stands for the basic input-output system. It is a small piece of the code that is present on a chip of the system board. When we turn on the computer, the bios is the first software that runs on the operating system. It will identify the hardware of the computer and then will connect it to the operating system. This process is called the boot process. By entering the bios setup utility, it will allow changing the process of the boot and its hardware settings. Only the experienced users must change the settings of the BIOS. The limitations that are present on the BIOS have led to the creation of the new interface called the UEFI. The UEFI is similar to the bios. The BIOS has a graphical user interface with network capability. It is also backward and forward compatible.
